[sheepdog] [PATCH] sheep: increase buffer while in cinfo collection

From: Liu Yuan <liuyuan at cmss.chinamobile.com>

Even with a 3 node cluster and only 1 vdi, killing one node and joining it back
the error message that "buffer too small" will pop out twice, this means 512 is
too small even for a single VDI cluster.

Making it as 4K will mitigat the problem a bit.
